The fractional CFO identity crisis

What our fractional CFOs don't do

Most “fractional CFOs” spend their day chasing data, cleaning reports, fixing operational gaps, and updating spreadsheets at midnight. At that point they're an outsourced finance department, not a CFO.

Not on your CFO's plate

Chasing missing receipts
Manually reconciling bank statements
Building the monthly close from scratch
Following up on AR collections
Updating spreadsheets at midnight before a board meeting
Cleaning vendor invoices in QuickBooks

Handled by our Launch + Foundation layers, so it never reaches your CFO.

Where your CFO's time goes

Decisions: should we raise now or wait two quarters?
Relationships: investor updates, board prep, partner negotiations
Strategy: pricing model evolution, market positioning
Growth: where to deploy the next $1M
Risk: what could break, and what we'd do if it did
Leadership: building the finance team you'll need in 18 months

What CFOs were hired for, protected at the Growth tier.

Every fractional CFO has to decide: am I building an advisory practice, or just becoming an outsourced finance department? Our pricing structure decides for us.

Frequently Asked Questions

What does a fractional CFO do for a startup?

A fractional CFO provides forward-looking decision analytics: financial modeling, board packs, fundraising strategy, spend guardrails, and capital planning. Unlike backward-looking reports, your CFO helps you make better decisions before you commit resources.

How much does a fractional CFO cost?

StartupCFO plans start at $179/mo (Launch) and go up to $799/mo (Growth with full CFO services). Compare that to $200K-$400K/year in total compensation for a full-time CFO hire (past $500K at growth stage) or $2K-$5K/mo for a traditional CPA firm’s advisory services.

When should a startup hire a fractional CFO?

You need a fractional CFO when you’re preparing for a fundraise, have board meetings that require financial reporting, need financial models for strategic decisions, or have outgrown what a bookkeeper alone can provide. Most startups from pre-seed to exit benefit from fractional CFO support.

Do I need a fractional CFO for my startup?

If you are heading into a raise, presenting to a board, or making runway and hiring decisions by gut, you likely need CFO-level help before a full-time hire is justified. Common triggers: preparing for a priced round, monthly burn above $75K, investor reporting requirements, and multi-scenario planning. A fractional CFO covers this in 10 to 40 hours per month; StartupCFO includes CFO support on Foundation and a full fractional CFO on Growth.

How is a fractional CFO different from a CPA?

CPAs focus on compliance, tax preparation, and backward-looking reporting. A fractional CFO focuses on forward-looking strategy: financial modeling, scenario analysis, fundraising support, and decision analytics. At StartupCFO, your CFO and CPA work as one team so compliance and strategy are connected.
